Cannot [still] use FNB Banking app and on-line banking while out of SA

Its been 12 days now and my FNB banking app does not work, ever since FNB changed the new banking app. I am overseas and cannot access this app. I laid a complaint and FNB did get back to me promising to look into the matter. However, I still cannot even use the banking app.

Secondly, I was told to use on-line banking instead. I have tried to transact, change my daily limits and make inter-account transfers to no avail. A "Daily limit exceeded" error repeats.

I reported this to FNB, to which they responded that it is a security measure since I am transacting after a long time from my lap top. I followed Mpho's instruction to remedy the situation but this has not worked. I am still unable to transact with either the banking app or on-line banking.

Is this how FNB works? 12 days without transacting? I am extremely upset at this poor service, to say the least.
